Title: Optical measuring device
IPC: G02B21/00
Filed: 1973-03-14
Abstract: 1415397 Photo-electric systems NIPPON KOGAKU KK 14 March 1973 [15 March 1972(2) 12173/73 Heading G1A [Also in Division G2] An optical measuring instrument includes an adjustable diaphragm having a portion formed as a reflective surface so that part of the light focused on the diaphragm by an objective lens passes through the aperture to a detector and the remainder is reflected to an optical viewing system. As shown, Fig. 1, in a microscope photometer, light transmitted by the specimen S passes through an objective lens 6 and a monochromatic filter 7, is reflected from mirror M1 and is focused by a relay lens L1 on to a diaphragm D which has an adjustable aperture to select the area of the image for measurement by a detector PM. The diaphragm blades have reflective surfaces and the light not passing through the aperture is reflected via lens L2, mirror M2 and prism reflector 8 to an eyepiece 9. The prism 9 may be retracted to allow a photograph to be taken by camera C. The diaphragm preferably comprises two glass plates which are silvered over three quadrants and arranged one in front of the other so that their unsilvered quadrants define a square aperture the size of which may be varied by moving the plates diagonally in opposite directions. One of the plates may carry a scale which is visible in the eye-piece image to indicate the size of the aperture. Since the surface of the glass plates reflects a small amount of light at their unsilvered areas a faint image can be seen within the aperture area. The device is used by closing the aperture down to its minimum size, positioning the specimen, opening the aperture to cover the desired area and then taking a measurement.  The diaphragm blades can also be made of metal with cut-out portions to define the aperture. The surface of the blades may be curved, e.g. by using spherically curved glass plates appropriately silvered. The arrangement may also be used in an astronomical telescope or as an I.R. radiation thermometer or image device.

Title: Improvements in or relating to the production of coloured artificial textile materials
IPC: D01F2/28
Filed: 1932-04-28
Abstract: Cellulose esters or ethers; dyeing; regenerated celluloses, dyeing; inorganic colouring matters, dyeing with; printing.--Dark coloured artificial textile materials, such as cellulose esters or ethers or regenerated celluloses, are obtained by applying colouring matters having direct affinity for the materials to such materials already coloured a grey or like neutral shade due to particles of inorganic pigment distributed throughout the substance thereof.  The process enables the production of dark shades with the use of relatively small amounts of the direct dyeing colouring matters with the advantage that the dyeings are fast to rubbing.  The colouring matter may be applied uniformly or locally and discharge effects may be obtained with the aid of discharging agents applied before or after the colouring matter. Such discharging agents may contain suitable additional colouring matters.  Specified pigments are carbon black and magnetic oxide of iron and the pigmented filaments may be obtained by incorporating 0.5--1 per cent of carbon black or 3--4 per cent of magnetic oxide of iron, based on the weight of the filament, in the solutions from which the filaments are spun.  Differently pigmented filaments or pigmented and non-pigmented filaments may be incorporated in a fabric to obtain cross dyed effects.  The following examples are specified.  (1) A spinning solution containing cellulose acetate and 0.6--0.7 per cent of finely divided carbon black is dry spun to obtain grey filaments which are then dyed in a soap bath with temperature rising to 70--80 DEG  C. containing in dispersion 1 - amino - 2 - methylanthraquinone, 4 4 - nitro - 2 - methoxybenzene - azo - diethylaniline, a mixture of 1 : 4-di-(methylamino)-anthraquinone and benzene-azo-benzene-azo-phenol, or 1 - amino - 4 - anilido - 5 - oxyanthraquinone (cf. Specification 402,392) to obtain nigger brown, deep maroon, deep bottle green and deep navy blue shades respectively.  (2) 3.5 per cent of finely divided magnetic oxide of iron is similarly incorporated in cellulose acetate filaments and yarn or fabric therefrom is then dyed in a soap bath with temperature rising to 70--75 DEG  C. containing finely dispersed p-nitrobenzene-azo-p-xylidine to obtain a rich brown shade. (3) Cellulose acetate yarn having carbon black or magnetic oxide of iron incorporated in the filaments as in (1) or (2) is woven into a warp of viscose artificial silk and the fabric is then dyed a solid shade of deep brown by a mixture of 1-amino-2-methylanthraquinone and Chlorazol nigger brown; alternatively the cellulose acetate may be dyed deep puce and the viscose yellow by a mixture of 4-amino-1-oxyanthraquinone and Chrysophenine G.  Specification 346,511 also is referred to.  The Provisional Specification refers to the use of colloidal metals as inorganic pigments.

Title: Apparatus for lifting and advancing a signature
IPC: B65H5/00
Filed: 1976-03-26
Abstract: 1495108 Feeding sheets MASCHINENBAU OPPENWEILER GmbH 26 March 1976 [4 April 1975] 12355/76 Heading B8R Signatures, e.g. transported through collecting, glueing and stitching stations, are transferred from a saddle 11 to clamps 42a, 42b, on rotating wheels 21a, 21b by reciprocable lifting tongues, 16 which accelerate them to the speed of the wheels. The signatures are then held between wheels 21a, 21b, 22a, 22b and toothed endless belts or chains, 23a, 23b, 24a, 24b, released by the clamps, cut and edge trimmed, transferred to a table 30 and finally moved on to a conveyer belt 28. A plurality of tongues 16 are provided and are adjustable for spacing so as to engage the ends and middle of a signature 12 on the saddle, when projected through a slot 15 at the saddle vertex. The tongues are reciprocated via levers actuated by a cam 82 and follower 81 mechanism. A device is provided for deactivating tongues which would foul the clamps if projected. The drive which rotates the wheels or the associated belts or chains is linked to the drive for cam 82 so that a lifted signature attains the speed of the wheels as it abuts stops, e.g. 43b, Fig. 5 projected from the surfaces of the wheels 21a, 21b in the vicinity of the clamps. The clamps then close on the signature which is transported to the nips of the belts. The stops serve to widen the nips between the outermost belts 23a, 23b and the associated wheels 21a, 21b until the signature is well into the nips. The stops are then retracted, the clamps released and the signatures additionally held by inner belts 24a, 24b. Cutter discs 29a, 29b, 31a, 31b then cut the signature into two and trim the edges. A pivotable arm 45 facilitates signature transfer to the wheels.

Abstract: 1430627 Peltier cooling devices INTERNATIONAL PROMOTION & ENG. SA 14 March 1973 [29 March 1972 22 Nov 1972] 12362/73 Heading H1K Apparatus for applying cold to a living body comprises (Fig. 1) a cylindrical casing 1 closed by a plug 2 with a peripheral groove and sealant ring, flanged to bear against the casing end. A battery 6 connected over push switch 9 secured to a cylindrical e.g. aluminium thermal mass 13 within the casing energizes a Peltier effect thermo-e ement 14 mounted on the end of the mass 13 to present a face which develops cold for application. Mass 13 protrudes from the casing and is covered by a cap 15 retaining the mass over ring 16; with a central aperturethrough which the element 14 protrudes. Terminals 17 disposed between switch and battery and accessible through apertures enable the battery to be connected to a charger (not shown) over a clip 18 engaging the casing with connecting pins contacting the terminal 17 (Fig. 4). In a modification (Fig. 6, not shown), a pyramidal thermal mass constitutes the body of the apparatus, and is hollowed out to contain the battery. A thermoelement energized therefrom is soldered to the apex which is covered by a plastic cap apertured for the cold face. The opposite end of the body is mounted' on a base enclosing a battery charger and mains lead. A cross-member within the hollow retains the battery and has a double socket engaging plugs on the charger, while it also carries a pressel switch and an indicator lamp. In a further modification (Figs. 8, 9) a cylindrical casing 1b is supported on stand 27b, with the thermoelement 14b presenting its cold surface through an aperture of the tapered apex with a cooling mass 13b to which the hot face of the element is soldered, screwed to the outer casing with a ring of dependent radial fins 45 aligned with orifices 46 of the casing. A central motor 48 retained by the fins and ring 49 drives a fan 52 circulating coolant air from further orifices 52. Battery 6b carried in sleeve 54 is positioned below the motor, and the body rests on base 17b containing a charger connected over pins 35b and sockets 34b. A pressel switch 9b controls energization, and a reversing switch 56 controls direction of current so that the outer face of the thermoelement may alternatively develop heat. In a further modification (Figs. 10, 11, not shown) a cascade of four thermo elements of progressively decreasing sizes generates cold, and the motor drives a double fan, while a temperature indicator responds to a thermocouple in the cold applying surface.  Dry batteries may replace rechargeable batteries (Fig. 12, not shown) while the device may be energized directly over a cable from a power unit comprising battery-charging circuit, reversing switch, on/off switch, and a skin temperature measuring probe; while the cold generator may incorporate a tapered, e.g. silver, applicator partly enclosed in an evacuated glass envelope (Figs. 12, 13, not shown).
Patent GB-474402-A (GB)
Title: Improvements in or relating to cellulose derivative staple fibre yarns
IPC: D01F2/28
Filed: 1936-05-01
Abstract: Continuous filament yarns having a basis of organic derivatives of cellulose are converted to staple fibre yarns by a direct conversion process in which the yarns are not submitted to breaking tension, and thereafter subjected to treatment with a hot aqueous medium in the absence of any substantial tension so as to permit crinkle to develop in the fibres.  By direct conversion process is meant a process in which the yarn does not lose its continuity at any stage from the continuous filament yarn to the staple fibre yarn.  Examples of such processes are those of Specifications 424,683, 424,752, 424,830, and 424,879, [all in Group IX].  The yarn may be subjected to any other process designed to impart crinkle to the material, for example, the staple fibre yarn may be subjected to a relatively high degree of twist, the twist set, and the yarn finally untwisted.  Suitable treatments with hot aqueous media are treatments with wet steam, or boiling or almost boiling aqueous media which may contain a wetting agent or a substance such as a salt or sugar which will reduce the loss in lustre.  By working under pressure, the treatment may take place at temperatures above 100 DEG  C.  The materials constituting the yarn may be cellulose acetate or other cellulose organic ester, or a cellulose ether or ether-ester, and the yarns may be associated with filaments of other kinds, e.g. natural silk or regenerated cellulose filaments.  It is advantageous to employ yarns containing filaments of flat cross-section obtained, for example, by spinning a solution of cellulose acetate in acetone in concentration of 24 per cent or lower.  The yarns obtained may be doubled together by an operation involving applying a light twist reverse in direction to any initial twist in the yarns, and may be in this condition at the stage when the yarn is subjected to treatment with the hot aqueous medium.  Specifications 246,879, 260,312, [both in Class 2 (ii)], 424,880, 442,073, [both in Group IX], 459,781; and 464,981, [Group IX], also are referred to.
